Ka of strong acid

Postby Savannah Mance 4G » Sat Jan 25, 2020 7:52 pm

Is the Ka of a strong acid like HCL just 1 since it fully dissociates?

I believe it will be a lot greater than 1 because there will be an abundance of products compared to reactants; therefore the Ka will be extremely large.

Strong acids have Ka values which are many times larger than 1. For comparing two acids, the one with the higher Ka value is the one which is more dissociated and is therefore relatively stronger.

Im guessing its more than one since Ka will usually be [conjeguate base][H30+]/[Strong acid] and [H30+]=[strong acid]
